CR-410C Coffee Index Colorimeter

The CR-410C coffee colorimeter measures the color of coffee easily and accurately. It can perform these measurements on a wide variety of coffee: whole green beans, roasted beans, and roasted coffee.

A The colorimeter is used to measure coffee bean color so that you don't have to use a bulky and expensive instrument. It also is more accurate than trying to assess coffee bean color visually. The CR-410C is an affordable and portable option. The CR-410C uses the SCAA specialty coffee index to calculate the color, roasted level (light, medium, medium-dark, dark), the difference from a standard, and pass/fail information. Additionally, it includes our Food Color Indexing Technology (FCIT).

The CR-410C is capable of measuring whole bean, lyophilized, powder and instant coffee forms. This user-friendly instrument also boasts a much lower cost for maintenance than its competitors.
